Abstract
The present study focuses' on mechanical characteristics of reinforced concrete (RC) panels under in-plane shear stress with ultimate strength determined especially by concrete failure. Monotonic loading tests were conducted using 32 RC panels with concrete cylinder strength, reinforcement ratios and load combinations with axial compression as parameters. The principal factors governing constitutive law of concrete were studied from the above test results. As the result, it is concluded that the reduction of concrete compressive strength under in-plane shear stress depends on not only the principal tensile strain, but the cylinder strength and axial compressive forces as well.
